List Description

The Malay-Indonesian Archipelago is the largest group of islands on the earth. Stretching from Sumatra to New Guinea, it includes the world's 2nd, 3rd, 5th, 11th, and 13th largest islands. All of the major islands in the archipelago are mountainous and rugged, crowned by the ranges of New Guinea, which features the world's highest island mountains.

Most of the peaks on these islands are volcanoes, and many are active. The notable exceptions are the non-volcanic high ranges of New Guinea and Borneo, but the island arc that includes Sumatra, Java, Bali, Lombok, and the Nusa Tenggara islands has one of the densest concentrations of high volcanoes anywhere.
